(PhysOrg.com) -- Battery life and driving range are two sticky phrases in discussions about why EVs have yet to hit mainstream use. Drivers still feel skittish about the idea of setting out on longer trips on batteries lasting ...

Liquid metal batteries, invented by MIT professor Donald Sadoway and his students a decade ago, are a promising candidate for making renewable energy more practical. The batteries, which can store large amounts of energy ...

(Phys.org)—Globalfoundries has made an announcement that amounts to a direct challenge to Intel, in the latter's race to get further ahead in the mobile device ecosystem. Both Globalfoundries and Intel will be racing for ...

Hybrid electric vehicles, cell phones, digital cameras, and the Mars Curiosity rover are just a few of the many devices that use rechargeable lithium-ion batteries. Now a team of Penn State researchers has a simple mathematical ...

(PhysOrg.com) -- You can preorder the first Alex Reader today... finally! Alex, the first Google Android-powered eReader will ship to preorders in mid-April, five months after its announcement made a huge splash last October. ...

Better batteries that charge quickly and last a long time are a brass ring for engineers. But despite decades of research and innovation, a fundamental understanding of exactly how batteries work at the smallest of scales ...
